Filed: 1986-11-08
Abstract: PURPOSE:To provide a CVD film of uniform film quality having no particular irregularity in density by disposing at least one heat insulating material respectively under a susceptor and on the outer periphery from the susceptor to a high-frequency electrode. CONSTITUTION:One or more heat insulating materials 70a-70c are disposed under a susceptor 60, and one or more heat insulating materials 80a-80c are disposed which surround the outer periphery from the susceptor 60 to a high-frequency electrode 51.
